On April 23, the security consulting firm Independent Security Evaluators (ISE) published a document concerning a number of unsound public and private key pairs tied to the Ethereum blockchain. The probability of chance needed to crack 256-bit encryption would take years for hackers to access random private keys. However, ISE recently queried 49,060 ETH transactions which found 732 “weak” public keys, essentially revealing the corresponding private keys. See more for yourself here.
